The rash sounds similar to one I got in early April 2023 right after a positive test and being sick after my spouse brought COVID home from a mandatory in-office 3 days of meeting. (He took Paxlovid; I had a script for it and tried one dose once I tested positive 2 days after he did; bad reaction and had to stop.)
Three diff docs including a dermatologist didn't connect it to COVID and still don't - "we've never heard/seen that before". I had 6 different topical salves to try. One of the rashes cleared; the other larger one never has. PLUS I developed horrific issues w/ my feet, esp the bottoms of my heels - they cracked - and now tho' they are, after 15 months, only cracking a bit, the burning and pain are like nothing, even after years on my feet working, I'd had before.
That and a continuing rash on one side of my mouth (same side as the leg rash) that has no apparent other causes or causations. That is, nothing brings it consistently on or makes it stop.
Others have provided some insights. I suggest, if you've not, a dermatologist and a podiatrist tho' my experience says that you may not get any help. I now use a cortisone cream on my heels when they begin to crack.
My hope is your senses return and that you find some way to manage the rashes.
That you for your response. I was on the antibiotic Clindamycin 300mg after the diagnosis. My husband also tested positive at same time. He was on a steroid and Clindamycin and he recovered. He can smell and taste, no rash. My rash started to spread again over my left knuckles of my hand and below my thumb overnight. Now a spot appears on my right knuckle same location. My lower back above hip area broke out over night . It seems the rash stats on one side then mirrors on the opposite side. Very strange. I have never had skin problems. I did have chicken pox and measles as a child. As an adult I did have shingles 4 times. I am unable to take any vaccinations because of my allergies/ sensitivity. This morning my doctor prescribed a topical steroid. I am willing to try anything at this point. I did not even know I had the rash on my lower back my husband showed me. It is round red/ pink . Several spots. I do experience widespread burning pins and needles sensation of my skin. I talked to my insurance company an no go for a Mayo Clinic because they do not cover out of the state of Michigan. I asked about other places within my state and they suggested Munson Health system which I am already seeing? My doctors are wonderful it is the insurance company that is denying what they are wanting to do. The doctors have tried multiple times to work with them. I hope you feel better and receive the care you need. The medical system as a whole need to come together and try to find answers. Many people like us are suffering from after effects of COVID we need our voices heard. This is disrupting my life and wellbeing as with other people. It seems no one has an answer. All I have read is steroids and antihistamines. With all the scientific knowledge you would think they would know more. They put out vaccines quickly enough. What about treatment now? I wish a Mayo doctor would read this. Maybe they would have suggestions for my doctors. I am researching as much as I can. Thank you for your response it is greatly appreciated.
